Makefile override CFLAGS, so -fmacro/debug-prefix-map
optiions was omitted and binaries contains absolute
patch to sources.

+Subject: [PATCH] dtc: Fix Makefile to add CFLAGS not override
+
+Makefile override CFLAGS not extend them, so some of them
+missing. Sources builds out of kernel tree and probably not all
+options could be used (?). We need at least -fmacro-prefix-map/
+debug-prefix-map to eliminate absolute path in binaries.
